WebEx Meeting Manager 'atucfobj.dll' ActiveX Control Remote Buffer Overflow Vulnerability

WebEx Meeting Manager is prone to a stack-based buffer-overflow vulnerability because it fails to perform adequate boundary checks on user-supplied input. This issue affects the 'atucfobj.dll' ActiveX control library.

An attacker can exploit this issue to execute arbitrary code in the context of an application using the affected ActiveX control (typically Internet Explorer). Failed attacks will likely cause denial-of-service conditions.

'atucfobj.dll' 20.2008.2601.4928 is vulnerable; other versions may also be affected.

The vulnerable versions of the ActiveX control are hosted by WebEx meeting service servers running WBS 23, 25, and 26 prior to 26.49.9.2838.
